We can also update a drive that has been flashed with an earlier version
If you drop off the console the process will take about half an hour.

We have to open the console and will therefore void the warranty of the XBOX
Your XBOX 360 DVD Drive has firmware that includes a DRIVE KEY. The drive key is unique to each XBOX 360 and prevents you from buying a new drive and simply swapping it over with the drive in your XBOX 360. The Drive houses a control card that talks the DVD Drive and the console, it is this part of the DVD Drive that we update. During the update process we backup the original firmware onto our system and this ensures that if anything goes wrong during the update then we are able to write back the original firmware to the DVD.

Another advantage to the customer is that if for any reason in the future the drive fails then we will have a copy of your original firmware and drive key on file enabling us to fit a new drive with a matching drive key in place.
